Unused single-ended inputs must be held high or low to prevent them from floating.
PCLK input frequencies lower than 500 kHz force the SN65LVDS305 into standby mode. Input frequencies between 500 kHz and
3 MHz may or may not activate the SN65LVDS305. Input frequencies beyond 3 MHz activate the SN65LVDS305.
Period jitter is the deviation in cycle time of a signal with respect to the ideal period over a random sample of 100,000 cycles.
Cycle-to-cycle jitter is the variation in cycle time of a signal between adjacent cycles over a random sample of 1,000 adjacent cycle
pairs.
